摘要： Cellulose diacetate having improved resistance to delustering in hot water is produced by acetylation cellulose in the presence of a catalyst and then hydrolyzing (or ripening) the product to form secondary cellulose acetate; wherein the catalyst in the acetylated mixture is completely neutralized before about the middle of the hydrolysis reaction at the latest and thereafter hydrolysis is carried out at a temperature of about 110.degree. to 120.degree. C. while maintaining the concentration of acetic acid in the reaction mixture at about 67 to 78% by weight based on the total weight of the acetic acid and water, the relation between the hydrolysis temperature and the concentration of acetic acid being defined by the area between and including points A, B, C and D in FIG. 2.

摘要： A process for producing cellulose diacetate is disclosed which comprises the steps of:(a) pretreating and activating 100 parts by weight of cellulose, adding a mixture of 200 to 400 parts of acetic anhydride, 0 to 350 parts of glacial acetic acid, and 0.5 to 5 parts of acid catalyst, heating the reactants to a temperature from 50.degree. C. to 85.degree. C. at approximately a constant rate, maintaining this temperature for 3 to 20 minutes, thereby acetylating cellulose to form primary cellulose acetate;(b) neutralizing the acid catalyst in the reaction mixture containing primary cellulose acetate obtained in step (a), introducing steam under pressure into the system to change the temperature of the system to 125.degree. C. to 170.degree. C., and maintaining this temperature for 30 minutes to 6 hours, thereby hydrolyzing the primary cellulose acetate to accomplish ripening; and(c) flashing the ripened reaction mixture at a temperature of 125.degree. C. to 170.degree. C. by discharging same to the ambient atmosphere, recovering by condensation the gas generated during flashing having an acetic acid/water weight ratio of 70-80/30-20, and simultaneously cooling the remaining liquid reaction mixture to about 100.degree. C., thereby substantially stopping the hydrolysis reaction.

摘要： A saturated polyester obtained by a reaction of a polycarboxylic acid component comprising a polycarboxylic acid having 2 to 6 carbon atoms in the main chain (e.g. maleic anhydride), and a polyol component comprising a polyhydric alcohol having 2 to 4 carbon atoms or its condensate is used as a cement retarder. A retardative sheet can be formed by applying or impregnating a composition comprising the retarder and a tacky adhesive to a base sheet. By forming a predetermined pattern with the use of the retarder or sheet in a form, depositing a mortar composition, washing a surface of the hardened concrete, and washing out uncured mortar, a figure or a washing finished surface is formed on a surface of a concrete product.
